I have a 2007 S80 V8 but am posting here because of the engine shared with the XC90 V8. I am hoping that someone can share the torque specification and tightening sequence for the (20) 6mm hex bolts that fasten the intake plenum at the top of the engine. I am planning to replace the fuel pressure regulator and will be posting instructions and images for the procedure. Thanks in advance for your replies.
